Understanding RollerDrive CNC Technology

The RollerDrive CNC is a testament to Sankyo’s innovative spirit. But what exactly is this technology, and how does it revolutionize CNC machining? |

What is RollerDrive CNC?

The RollerDrive CNC is a circular table rotary axis designed to deliver motion without distortions. It’s engineered to maintain integrity even under the stress of cutting hard metals, making it ideal for high-precision machining.

How RollerDrive CNC Stands Out

Unlike traditional gears and torque motors, the RollerDrive CNC is resilient against external forces. Its impressive rotational accuracy of ±10 arc seconds and repeatability of less than ±4 arc seconds set it apart from the competition.

Key Features of RollerDrive CNC

The RollerDrive CNC boasts several key features that make it a game-changer in CNC machining.

Zero-Backlash Technology

At the heart of the RollerDrive CNC is its zero-backlash technology. This is achieved through the use of preloaded roller followers and needle bearing type roller followers.

Preloaded Roller Followers

The preloaded roller followers interact with the input shaft’s rib surfaces, eliminating backlash entirely. This ensures superior precision and rigor for both clockwise and counterclockwise rotations.

Needle Bearing Type Roller Followers

These roller followers transmit power through rolling rather than sliding, achieving an efficiency rate of over 90%. This rolling mechanism reduces wear and tear, improving the machine’s durability.

No Clamp Operation

Unique to the RollerDrive CNC is its no-clamp operation. Its mechanically rigid structure eliminates the need for clamp and unclamp times, common in conventional hydraulic systems. This not only saves energy but also enhances productivity through ultra-fast positioning—achieving a 90-degree rotation in just 0.4 seconds.

Perpetual Precision

Durability and maintenance-free operation are key features of the RollerDrive CNC. Its unique mechanism ensures it can operate for years without performance degradation—meaning no wear on internal parts and no need for regular calibration. This perpetual precision makes it a reliable choice for continuous, high-demand operations.
